Could you share steps for tomcat 7 on Ubuntu?

I want help in setting certificate for configuring tomcat 7 on Ubuntu.
I tried many things but not success only HTTP works.
Could you share server.xml, I am using this:

<Connector executor="tomcatThreadPool"
            port="8080" protocol="HTTP/1.1"
            redirectPort="8443" />
 <Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
            maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
            clientAuth="false" sslProtocol="TLS" />

What’s the problem instance on AWS and I opened 8443 but not connecting.
Installation process:

Hi @am0awad,

What’s the real domain name?

When you try to connect, do you see a browser error or does the connection simply time out?

Did you already successfully obtain a certificate and convert it into JKS format?

Based on the “connection refused” error, Tomcat is not listening on 8443.

What’s this show:

ss -tlnp


keytool -list -keystore /root/ -storepass pass

and please show your logs/catalina.out output for the most recent start as well.

keytool -list -keystore /root/ -storepass pass

keytool error: Keystore was tampered with, or password was incorrect

Well, it looks like either your keystore password is wrong in the configuration, or you haven’t set the keystore up at all.

I have to hop into a meeting now, but basically:

  1. Acquire a certificate using Certbot or another Let’s Encrypt client. Have you done this or not?
  2. Export the certificate you acquired from /etc/letsencrypt and import it into a keystore file that Tomcat can read
  3. Point Tomcat at that keystore file with the correct passphrase.

This post can help you with steps 2 and 3.

Hi @_az,

Solved thank you.
